If you're dealing with IBS or following a low FODMAP diet, one question that might pop up while planning your meals is—are potatoes low FODMAP? Good news! In most cases, potatoes can absolutely be part of your gut-friendly plate.
Potatoes are one of the most commonly consumed foods worldwide. They’re budget-friendly, filling, and can be cooked in countless delicious ways. But for those managing digestive health, understanding how potatoes fit into the FODMAP framework is essential.
Let’s dive into everything you need to know about potatoes on a low FODMAP diet—including which types are safe, what portion sizes to follow, and how to prepare them the right way.
What Are FODMAPs?
Before we get into the details of potatoes, it helps to know what FODMAPs are.
FODMAPs stand for Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols—types of short-chain carbohydrates that some people have trouble digesting. These compounds can ferment in the gut, leading to gas, bloating, abdominal pain, and irregular bowel movements—especially in those with Irritable Bowel Syndrome (IBS).
A low FODMAP diet, developed by Monash University, helps people manage these symptoms by eliminating high FODMAP foods and slowly reintroducing them to find individual triggers.
Are Potatoes Low FODMAP?
Yes, most potatoes are naturally low in FODMAPs, especially when consumed in the right portion sizes and without high-FODMAP toppings like garlic, onion, or milk-based sauces.
✅ Low FODMAP potato types include:
White potatoes
Red potatoes
Yellow potatoes
Purple potatoes
These varieties are FODMAP-safe when eaten in a serving size of about 1 medium potato (150g). They can be enjoyed boiled, baked, roasted, or mashed using FODMAP-friendly ingredients.

What About Sweet Potatoes?
Sweet potatoes are a bit more complex. While they’re full of fiber and nutrients, they do contain mannitol, a type of polyol, which is a high FODMAP compound.
✅ A serving of 75g (about ½ cup cooked) is considered low FODMAP.
❌ Larger servings can trigger symptoms in sensitive individuals.
So yes, sweet potatoes can be included in small amounts, but portion control is key.
How Cooking Method Affects FODMAP Content
You might be surprised to know that how you prepare potatoes can make a big difference in whether they stay low FODMAP or not.
✅ FODMAP-Friendly Cooking Methods:
Boiled or steamed potatoes with the skin on
Baked potatoes with olive oil or lactose-free butter
Mashed potatoes with lactose-free milk or plain water
Oven-roasted with garlic-infused oil (NOT fresh garlic!)
❌ High FODMAP Triggers to Avoid:
Garlic or onion added to potato dishes
Creamy sauces or toppings made with dairy
Fried potatoes in shared fryers or with wheat-based coatings
Tip: For garlic flavor without FODMAPs, use garlic-infused oil—it's safe and adds amazing taste.
How Much Is Too Much?
Even low FODMAP foods can become problematic in excess. That’s why portion control is a big part of the low FODMAP diet.
According to Monash University:
✅ White potato: Safe at 150g (1 medium potato)
⚠️ Sweet potato: Safe at 75g (about ½ cup cooked)
If you combine potatoes with other FODMAP foods, the total load can increase and lead to symptoms, even if individual ingredients seem safe.
Are Potatoes Low FODMAP & Nutritious?
Absolutely! Not only are most potatoes low FODMAP, but they also provide excellent nutrition:
Rich in potassium, which supports heart health
Source of Vitamin C and Vitamin B6
High in complex carbohydrates for long-lasting energy
Naturally gluten-free and fat-free
Potatoes can be a helpful part of a balanced, IBS-friendly diet—just stick to clean ingredients and watch your portions.
